Overview

Neucron is whitelabelled wallet infrastructure for fintechs. Wallets, payments, and agentic finance on every major rail, behind one API.

Whitelabelled wallet infrastructure for fintechs

Neucron is the wallet and payments infrastructure layer for fintechs. You bring your product, your brand, and your customers. Neucron provides the wallets, the key management, the compliance gates, and the money movement, invisibly, behind one API.

Everything in Neucron is built around a few ideas worth understanding before you write a line of code:

Start with the concepts

Concept	What you will learn
Blockchains as Rails	Why each chain is just a payment rail, and how Neucron abstracts them
Wallets & Keys	What a wallet actually is, minus seed-phrase anxiety
MPC Key Shards	How 2-of-3 shards make keys unstealable and unlosable
Custody Models	Non-custodial, custodial, and server-side MPC, and choosing per wallet
Accounts, Businesses & Teams	Individuals vs businesses, members, roles, granular permissions
Apps & Whitelabel	Sign in with Neucron vs fully embedded wallets under your own auth
Compliance Levels	KYC/KYB levels 1 to 4 and what each unlocks
Agentic Wallets	Apps + server-side wallets + MCP = governed AI agents with budgets

Then move money

Capability	What it covers
Invoices & Payment Links	Customers, invoices, branded payment links, partial and multi-asset clearing
Bills, Payouts & Approvals	Vendors, bills, scheduled payouts, amount thresholds, multi-approver and MFA policies
Treasury & Holdings	Business treasury and individual holdings, multi-wallet structures

And pick your rails

Reference	What it lists
Supported Networks	Live rails and the network roadmap
Asset Protocols & Types	Token standards, and when each is used
Assets: Live & Upcoming	The live support matrix and the asset roadmap

Ways to integrate

Neucron is documented across three companion surfaces. Use the one that matches how you build:

Surface	Best for	Documentation
REST API (this space)	Direct HTTP, OpenAPI, custom clients	API References below
TypeScript SDK (@timechainlabs/neucron-ts-sdk)	Typed Node / web / React Native backends	Neucron TypeScript SDK
MCP Server	AI agents & LLM tools (neucron_* tools)	Neucron MCP

All three talk to the same Neucron backend. Auth tokens and business context work the same way across them.
